Discover how Minetek’s sound attenuation on the Liebherr R 9800 achieved a 33% sound reduction, significantly reducing the machine noise output while maintaining OEM airflow. This ensured that this coal mine met regulatory noise compliance whilst operating 24/7 without any downtime due to overheating. This project not only made the R 9800 the quietest machine on site but also strengthened this mines relationship with the Muswellbrook community.

Product/Scope – Sound attenuation on the Liebherr R 9800 Excavator
Brief
This coal mine faced pressure to meet strict noise requirements imposed by the EPA. In order to maintain a strong relationship with the nearby community of Muswellbrook, this mine has invested heavily in sound solutions designed to reduce noise and meet regulatory compliance. Minetek has been able to support this mine through this journey, allowing operations to run sustainably both day and night through the life of the mine.
Challenge
Minetek's sound solution needed to reduce the noise output of the Liebherr R 9800 down to site level noise requirements, without comprimising OEM airflow or accessablity for machine maintenance.
Solution
Ninetek reduced the noise output of the Liebherr R 9800 by one-third, enabling the machine to operate maximum output whilst meeting stringent site noise requirements, without any downtime due to overheating. With ease of access for maintenance, Minetek’s sound suppression solutions ensured sustained performance and compliance, enhancing operational efficiency and worker safety.
